The first implementation was way too complicated and prone to bugs.
This is much more simple flexible; first off, std::function is now used
instead of a raw function pointer, so lambdas and binds are fair game
which is great for scripting. Second, callbacks for all stacks are
executed. It is up to the callback target to ensure correct behavior.
Get rid of `iConditionBitFlag` in favor of a system of individual buff
objects that get composited to a bitflag on-the-fly.
Buff objects can have callbacks for application, expiration, and tick,
making them pretty flexible. Scripting languages can eventually use
these for custom behavior, too.
TODO:
- Get rid of bitflag in BaseNPC
- Apply buffs from passive nano powers
- Apply buffs from active nano powers
- Move eggs to new system
- ???
Was getting frustrated by the inconsistency in our include statements,
which were causing me problems. As a result, I went through and manually
re-organized every include statement in non-core files.
I'm just gonna copy my rant from Discord:
FOR HEADER FILES (.hpp):
- everything you use IN THE HEADER must be EXPLICITLY INCLUDED with the exception of things that fall under Core.hpp
- you may NOT include ANYTHING ELSE
FOR SOURCE FILES (.cpp):
- you can #include whatever you want as long as the partner header is included first
- anything that gets included by another include is fair game
- redundant includes are ok because they'll be harmless AS LONG AS our header files stay lean.
the point of this is NOT to optimize the number of includes used all around or make things more efficient necessarily. it's to improve readability & coherence and make it easier to avoid cyclical issues
Group structures are used now. Adds more checks in some places but simplifies things overall.
We can expand this system to entities as well now pretty trivially.
Start by replacing `hitMob` with `takeDamage` interface function.
Simplify `pcAttackChars` a little by utilizing the new interface, then add more interface functions as needed.
A lot of the combat logic is tied to the `Mob` class. Need to start moving stuff over to CombatNPC.
Mobs and CombatNPCs still need theirs in order to properly set their
roaming and spawn coords. Assignment of the latter has been moved to the
CombatNPC constructor, where it should have already been.
Storing certain things in appearance data and others in their own fields
was gross. Now everything is stored on the same level and functions have
been added to generate appearance data when it's needed by the client.
This fixes an issue where there server would start up fine even if NPC
types from a later build were found in the gruntwork file. Because of
the semantics of the C++ array indexing operator, the index into NPCData
in loadGruntworkPost() would silently create extra entries in the
nlohmann::json array, which would break future NPC type limit checks and
subsequently crash the server at the next invocation of /summonW, and
likely other places.
We fix this by refusing to start the server if any invalid NPC types are
found, because simply skipping them in the gruntwork file would silently
omit them from further writes to the gruntwork file, which would be
undesirable data loss.
The server now checks the libsqlite both at compile time and on server
startup. The version the executable was built with and the one it's
running with may be different, so long as they're both at or above the
minimum supported version. One or both version numbers are printed on
startup, depending on if they're identical or not.
The compile-time ("Built with") version depends on the sqlite3.h header
used during compilation, while the runtime ("Using") version depends on
either:
* The sqlite3.c version used during compilation, if statically linked.
(Which may be different from the header version and still compile and run
fine.)
* The version of the libsqlite3.so or sqlite3.dll that the server
loaded, if dynamically linked. Version mismatches here are normal,
especially on Unix systems with their own system libraries.
The current minimum version is 3.33.0, from 2020-08-14, as that's the
one that introduced the UPDATE-FROM syntax used during login by
Database::updateSelectedByPlayerId().
Also rearranged the prints and initialization calls in main() slightly.
Previously, only loadGruntworkPost() would be skipped if the gruntwork
was null, but it was never null at that point because loadGruntworkPre()
would inadvertently create gruntwork["paths"] when it indexes it to
iterate through it.
Now, the gruntwork loading messages will no longer be misleadingly
printed to stdout when there isn't a gruntwork file.
UBSAN complains about the casting approach because it loads a 64-bit
integer from the defaultKeys string which isn't guaranteed to be 64-bit
aligned, which is undefined behavior.
